Sadly, this impressive “pusher” was scrapped between 1952 and 1956… It should be noted that the Alleghenies were some of the most powerful steam locomotives ever built. At 40 mph they could generate 7500 hp. This power was only exceeded by the PRR Q-2 Class (7987 hp). By contrast, the UP Big Boy could generate a maximum of 6200 drawbar hp.
